Each plant is adapted to live in its environment. One adaptation is the type of root system the plant has. Certain plants are meant to grow in certain areas. The root system determines where a plant will grow and adapt best to the environment because it is an adaptation.
The plant itself pushes its roots outward in different directions. The plant can sense a water source and grow roots in that direction. Also, the roots can grow in any direction, but rarely they grow up because of gravity.
Presence of sun or light
The roots of most plants grow towards the pull of gravity.
Plant roots grow whatever direction is necessary to acquire the largest quantity of water most easily. For example, a tree in the desert will grow roots very, very deep to get to the resources of water there. However, if you constantly water a tree, its roots will grow sideways just below the surface of the soil (which, by the way, can cause it to be unstable in high wind, and even blow over).
Climate?
shallow roots extend away from a plant long; thinck roots that grow deep
Yes, geotropism DOES determine the direction of growth. Negative geotropism is when a section of the plant grows upwards. For example, stems grow upward. Positive geotropism is when a section of the plant grows downwards. In this case, a plant's roots would be the perfect example.
The roots of most plants grow towards the pull of gravity.
Downward
Outwards.

the roots would grow toward the trees to get its food and water
Well, roots will always grow down due to geotropism. It is caused by the statocytes in the root cap. They sense the force of gravity and grow down according to it. But if the root does not have a root cap, then the plant will not necesarily grow down. And if the seed is layed on a flat place like a counter, then the roots will grow any which-way. I did an experiment on this for the science fair. I found it at: http://www.sciencebuddies.org/science-fair-projects/project_ideas/PlantBio_p034.shtml
yes Light has more effect. light would affect the direction of foliar growth, the direction of root growth is determined by gravity (with a few exeptions)
They grow toward the pond in order to get food and water.
The type of climate in a given area determines which plant will grow there.
The amount of precipitation determines which plants to grow where.
